PROBLEME ENREGISTREMENT

Greetings @Clara_Perinaud2174,

I appreciate you sharing the screenshot, and I apologize for the trouble you're experiencing. Could you verify if you are using InDesign 21.0.1, which is the most recent version, and also let me know the macOS version you are on?

Meanwhile, please attempt to rename the CEP folder to CEP.old from the following directory on your Mac: /Library/Application Support/Adobe. If the problem persists, rename the UXP folder to UXP.old from these two locations: /Library/Application Support/Adobe and ~/Library/Application Support/Adobe. After doing this, restart InDesign and try saving again.

If that does not resolve the issue, please consider manually resetting InDesign preferences by following the instructions in this guide: https://adobe.ly/3LNQsbW

If the dialog remains black after trying the previous steps, you might want to explore these related threads where other users have found solutions to the same problem. The suggestions provided there may be useful, so please check them out and let me know what you discover:
